    Sammanfattning : Denna studie handlar om textila materials brännbarhet och antändlighet, framförallt bäddtextilier i bomull. Idag finns det lagkrav på att utföra antändlighetstester enligt SS- EN ISO 12952-1:2010 på bland annat fyllda bäddtextilier, till exempel täcke och kudde. LÄS MER

  2. 7. Remediation of Contaminated Groundwater Using a SpinChem® Rotating Bed Reactor : Competitive Sorption of Metal(loid)s in Complex Solutions under Varying Geochemical Conditions

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Pär Alapää; [2018]
    Nyckelord :Groundwater Remediation; Competitive Sorption; SpinChem;

    Sammanfattning : The potential of utilizing a new form of chemical processing technology called SpinChem® Rotating Bed Reactor (RBR), in combination with different reactive materials, for the purpose of remediating multi-contaminated aquifers under changing environmental conditions, was investigated using laboratory studies and geochemical models. Four different reactive materials, or combinations thereof, were tested: heat-treated peat powder combined with zero-valent iron (ZVI); IronPeat, which consists of peat powder coated with a ferriferous hydrosol (FFH); and a powdered steel waste product.

  3. 8. Modelling adsorption rate in a rotating bed reactor

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jonathan Jonsson; [2018]
    Nyckelord :computational fluid dynamics; fluid mechanics; cfd;

    Sammanfattning : SpinChem AB designs rotating bed reactors (RBR:s) that are used to conduct reactions between solid and liquid phase. In this work a model have been developed that predicts the performance of the S2 RBR. Coupled with simulations the model could be used to improve current and future RBR designs. LÄS MER

  4. 9. Pyrolysis of Waste Electrical and Electronic Equipment (WEEE) Plastics for Energy and Material Recovery

    Master-uppsats, KTH/Energiteknik

    Författare :Ioannis Asvestas; [2018]
    Nyckelord :;

    Sammanfattning : The society is striving to tackle the over-extraction of Earth´s resources due to the ongoing population rise. The increased needs of energy and material resources leads to a growing volume of materials waste, which include a variety of dangerous pollutants among them. LÄS MER

  5. 10. Evaluation of mechanical and microstructural properties for laser powder-bed fusion 316L

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Philip Eriksson; [2018]
    Nyckelord :Additive Manufacturing; Laser Powder-Bed Fusion; L-PBF; 316L; Mechanical Properties;

    Sammanfattning : This thesis work was done to get a fundamental knowledge of the mechanical and microstructural properties of 316L stainless steel fabricated with the additive manufacturing technique, laser powder-bed fusion (L-PBF). The aims of the thesis were to study the mechanical and microstructural properties in two different building orientations for samples built in two different machines, and to summarize mechanical data from previous research on additive manufactured 316L.
